In line with KEF's obsessive pursuit of ever-higher sonic resolution, M100 Hi-Fi earphones deliver a noticeably fuller, crisper and more accurate response, with each vocal or instrument clearly differentiated. With ingeniously damped full-range 10mm neodymium drivers and a unique angled chamber engineered to minimise distortion, the listening experience has the intensity and detail of hearing the original live performance. A masterpiece of KEF's innovative acoustic engineering in miniature, M100 Hi-Fi earphones share the same design integrity and build quality as the rest of the M Series range. The aluminium 'race-track' casing is precision machined with diamond-cut chamfered edges, and the internal components are exhaustively tested for consistently accurate response. Nothing is overlooked, right down to the environmentally friendly new benzene-free production process - another KEF 'first'. There are four cool colour finishes to choose from: Racing Blue, Sunset Orange, Titanium Grey and Champagne Gold.
